Yonex VCore 100 (300) features the new advanced technologies to help players implement speed and spin into their game. The ISOMETRIC technology helps to create a 7 percent larger sweet spot to maintain power and improve control. At the top of the Head, the grommets are embedded in an Aero Trench, which hides the grommets and further reduces air resistance. Namd graphite has been added for improved flex and fast frame snapback.
Liner Tech expands the sweet spot horizontally and keeps the main strings straighter reducing the entry angle of the grommets. The VCORE 100 is 300g strung, with an RA stiffness rating of 69.
Round that out with a controlled 16×19 string pattern and you get the makings of a comfortable performance racket.
